I notice your list of supported font formats is incomplete:
        Apple's FONT/NFNT bitmap resources
        Multiple Master fonts
        Apple's *var extensions to truetype (essentially mm)

There is a stress test generation program available from fontforge which
will take a directory of normal fonts, mangle them, and make sure that
the library doesn't crash on them.
http://cvs.sourceforge.net/viewcvs.py/fontforge/fontforge/test/randomtest.c?rev=1.1&view=log
(initially designed for fontforge, but modified to work for freetype
too).

It is very difficult to come up with a general testsuite for font
rasterization. There are many possible "good" solutions, the "best" will
vary from display to display, individual esthetics are often different.
